Final Answer: 
Steps/Reasons/Explanation:
It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

Answer:
Point of intersection is (-2, -1).
Step-by-step explanation:
The diagonals bisect each other so we only need to find the midpoint of one of the diagonals. We'll use the diagonal qs:-
Midpoint = (-8 + 4)/2, (1 + -3)/2
= (-2, -1)
Check the picture below.
now, the diagonals cut each other in two equal halves, thus, the midpoint of GF is the same coordinates as the midpoint for EH, so let's check what the midpoint for GF is then
Write out the "rate" as follows: 84 cents / 6 ounces
Then reduce 84/6: 84/6 cents/oz = 18 cents/oz (answer)
Example...
4^x = 16
log(4^x) = log(16)
x*log(4) = log(16)
x = log(16) / log(4)
